Atmospheric environment PM2.5 monitoring device for engineering construction

Abstract

The invention provides an atmospheric environment PM2.5 monitoring device for engineering construction. The device comprises a dust equipment chassis (1), a light receiving element (2), a receiving plate (3), a scatter plate (4), a light emitting element ( 5), a first exhaust pipeline (6), a second exhaust pipeline (7), a first fan motor (8), a second fan motor (9), a first exhaust port (10), a second exhaust port (11), a first exhaust passage (12), a second exhaust passage (13), a first air inlet (14), a second air inlet (15), a first gas collection port (16), a gas supply passage (17), a second gas collection port (18), a gas distribution passage (19), a particle retention device (20), a data collection and storage system and a power supply system. The instrument can meet a self-cleaningfunction of the equipment under the heavy pollution condition of PM2.5. The PM2.5 concentration can be measured independently, or the PM2.5 concentration can be measured in a vehicle-mounted mobile manner.

Description

technical field [0001] The invention relates to the fields of engineering construction and atmospheric environment protection, especially the field of highway engineering, and specifically relates to a monitoring device for particulate matter (PM2.5) in the atmospheric environment used in engineering construction. Background technique [0002] The construction of expressways will inevitably have direct or indirect impacts on the environment to a certain extent, especially it will change the continuity and integrity of the existing natural environment and destroy the ecological balance of natural environmental protection. By installing various atmospheric environment monitoring probes and systems during the project construction process, the environmental pollution caused by project construction can be effectively supervised. But for linear projects like highway projects or railway projects, which are hundreds of meters away and obviously cover the entire line of atmospheric e...

Problems solved by technology

But for linear projects like highway projects or railway projects, which are hundreds of meters away and obviously cover the entire line of atmospheric environment monitoring points, not only the cost is high, but also the maintenance cost is very expensive. How can we develop a set of vehicle-mounted mobile devices and configure a The atmospheric environment PM2.5 monitoring device used in engineering construction can carry out mobile environmental monitoring according to the degree and demand of environmental pollution, which will greatly reduce the cost of atmospheric environmental monitoring
